Linq query to get the distinct values in a list

Question

Suppose this is my member class

class Member 
{
    public string CategoryId { get; set; }
    public string MemberName { get; set; }
    public int Distance { g         


        

Answer 1

This is similar to those above, however it is technically a one liner for those interested....

var queryResult= (from l in list
                  select new Member()
                 { 
                    CategoryId = l.CategoryId , 
                    MemberName = l.MemberName 
                    Distance = l.Distance
                 }).GroupBy(x=>x.CatagoryId).Select(z=>z.OrderBy(i=>i.Distance).First()).ToList();
